- Relocate webpack stuff to assets/build
- Switch all js to airbnb code style
- Update webpack to v2.0 (beta)
- Update all other dependencies
- Assets manifest uses relative path as key [1]
- Code should be compatible with Node 4.5.0
- All dependencies have been updated
[1]: Previously the assets manifest would use the basename of a file path as
its key when looking up a cachebusted file. This was to be consistent with
Sage 8. This change makes it so that the relative path is used instead.
To clarify, review the following example.
Before:
```
{
"main.js": "scripts/main_5f4bfc9a9f82291c6dea.js",
"main.css": "styles/main_5f4bfc9a9f82291c6dea.css",
"customizer.js": "scripts/customizer_5f4bfc9a9f82291c6dea.js"
}
```
After:
```
{
"scripts/main.js":"scripts/main_5f4bfc9a9f82291c6dea.js",
"styles/main.css":"styles/main_5f4bfc9a9f82291c6dea.css",
"scripts/customizer.js":"scripts/customizer_5f4bfc9a9f82291c6dea.js"
}
```
